Not able to add a record into Table created in Web Dynpro java application

[Former Member]

Dear All,

While creating a table, I have selected a context node and its attributes to be bound to this table.The properties of this context node are mentioned below

cardinality : 1..n

collectionType : list

selection 1..n

singleton false

typedAccessRequired true.

But in the Table created I not able to add/edit more than 1 row.

Would really appreciate if some 1 would help me out here

why do you keeping singleton to false? set it to default value true

Singleton:

property determines the parent-child relation.

if true: for each parent element, there is one child (i.e. 1 - 1)

if false: irrespective of parent, there is only one child ( Many to one).

Nikhil,

In my case i need the parent child relationship to be 1-many.How should I go about doing that?

[nikhil_bose · Accepted solution]

make singleton to true. it will work

Actually there is a correction in my previous post.

if singleton is true it is 1 - Many.

gridMode both

readOnly false

rowSelectable true

There is no manual settings needed. Its quite straight-forward.

1) create a node TableNode. don't change default values

2) add attribute Name of type string.

1)place a table UI element in the view

2) bind data source property

3) create a table column and table cell editor as textview

4) bind value to TableNode-Name

now, we will populate some values.

in the wdDoInit() place the code

IPrivate<YourCompName>View.ITableNodeElement   element;
String values[]={"One","Two","Three","Four"};
for( int i = 0; i<values.length; i++) {
  element = wdContext.createTableNodeElement();
  element.setName(values<i>);
  wdContext.nodeTableNode().addElement(element);
}

hi try this code.cardinality 0.n

IPrivateFormView.ITableElement ele=wdContext.createTableElement();

ele.setId(wdContext.currentContextElement().get<valueattr>());

ele.setName(wdContext.currentContextElement().get<valattr());

ele.setSalary(wdContext.currentContextElement().getvalattr());

int size = wdContext.nodeTable().size();

for(int i=0;i<size;i++)

{

if(wdContext.currentContextElement().getId()==wdContext.nodeTable().getTableElementAt(i).getId())

{

wdComponentAPI.getMessageManager().reportWarning("record already inserted");

return;

}

}

wdContext.nodeTable().addElement(ele);

wdComponentAPI.getMessageManager().reportSuccess("record suceefully installed");

Thanks if helpful give me points

No new information but asking for points...

Rows in the table are created from elements in the context node. You have defined the cardinality of the context node as 1:n, this will give you one element automatically. To get more elements (rows) you have to create and add elements to the node using code like

I<YourNode>Element e = wdContext.node<YourNode>.createAndAdd<YourNode>Element();
e.setXYZ(value);

Hi Roshan,

Change the properties like this and try:

cardinality : 0..n

collectionType : list

selection 0..n

singleton true

typedAccessRequired true.

Your problem is to add the elements to this node, I guess you are taking input from the table UI element. Then you must create elements to this node.

IPrivate<viewname>.I<nodename>node node = wdContext.node<nodename>();
for(int i=0; *i<10* ; i++)
{
IPrivate<viewname>.I<nodename>Element ele = node.create<nodename>Element();
//If you want you can set you attributes here
node.addElement(ele);
}

10 elements are created.

You can create & add elements like this.

Siva

Hi,

Try with changing the cardinality.

if you put the code you are using, it will be helpful to findout

Pradeep,

I did change the cardinality but that hasnt worked.I havent coded anything as of now, all changes in the setting are being made in the SAP netweaver development studio.The coding part i would look into later, where i need to put in my business logic.I am doing a POC on Web Dynpro bacis features, without considering the ABAP part.

Thanks for the reply mate
